The 1950 Bentley Mark belongs to the immediate postwar era when British luxury cars balanced traditional craftsmanship with increasingly modern road manners. For many owners, tire choice is part of preserving that character, because this Bentley sits right at the intersection of older bias-ply practice and later radial touring expectations. The 1950 Bentley Mark uses either a 650-16 bias-ply tire or a 185R16 radial, both on 16-inch rims. That opens the door to choices in blackwall or wide whitewall styling, traditional bias-ply series, or well-known European-style radial options. The right direction depends on whether the priority is period-style presentation, road-use manners, or a restoration-minded balance of both.
Which Tire Size Is Right for The 1950 Bentley Mark
The 1950 Bentley Mark uses two primary tire sizes, and the difference is tied to construction rather than wheel diameter, since both fit a 16-inch rim. The first step is deciding whether the car is being kept with a traditional 650-16 bias-ply setup or fitted with a 185R16 radial approach, then confirming the actual wheel dimensions before choosing among available tire styles and series.
185R16 is a Euro-metric radial size in which 185 identifies the nominal section width in millimeters, R denotes radial construction, and 16 is the rim diameter in inches. On a 1950 Bentley Mark, this size represents the more modern of the two primary fitment directions while still staying within a traditional 16-inch wheel format. Available choices include Michelin, Avon, and Vredestein blackwall radials across series such as Michelin X Radial, Turbosteel CR6D, and Sprint Classic. It suits owners who want a vintage-compatible radial size while keeping close attention on wheel width and overall vehicle setup.
650-16 is a numeric bias-ply size, with the 650 referring to an approximate 6.50-inch nominal section width and 16 identifying the wheel diameter. For the 1950 Bentley Mark, it preserves the traditional bias-ply construction associated with many restoration-oriented prewar and immediate postwar tire presentations. This size offers the broadest visual variety, including blackwall and wide whitewall options from brands such as BFGoodrich, Firestone, Goodyear, Coker Classic, Garfield, Lester, and others. It is the size to evaluate when period-style appearance and classic bias-ply character matter as much as simple dimensional fitment.
Fitment is straightforward here because the covered sub-model uses the same two primary tire sizes. Checking the exact sub-model still matters, since the real decision is whether the car is being kept on 650-16 bias-ply tires or set up with 185R16 radials on 16-inch wheels.

1950 Bentley Mark VI
The 1950 Bentley Mark VI uses the same two fitment paths found across this application: 650-16 bias-ply or 185R16 radial on a 16-inch rim. That means tire selection centers on construction, appearance, and wheel compatibility rather than chasing a unique sub-model-only size.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Common questions for the 1950 Bentley Mark usually come down to choosing between 650-16 bias-ply and 185R16 radial tires, understanding 16-inch rim fitment, and selecting the right appearance and construction for restoration or regular road use.
Tire Size & Fitment
What tire size fits a 1950 Bentley Mark?
The 1950 Bentley Mark uses two primary tire sizes: 650-16 in bias-ply construction and 185R16 in radial construction. Both sizes use a 16-inch rim, so the main fitment question is not wheel diameter but which construction and size format best match the car’s current setup and intended use.
A Bentley that still carries restoration-oriented wheels and a traditional look may point you toward 650-16, while a car set up for radial touring may be using 185R16. Before selecting either size, confirm the wheel width, check for any past wheel changes, and make sure the tire choice matches the appearance and road-use goals for the car.
What size rim does a 1950 Bentley Mark use?
The tire fitments for a 1950 Bentley Mark are built around a 16-inch rim. Both the 650-16 bias-ply size and the 185R16 radial size share that same rim diameter, which simplifies one part of the selection process even though the two tire constructions are quite different.
Rim diameter is only the first checkpoint. The next step is confirming actual wheel width, because several available tires within these sizes call for different rim-width ranges. That becomes especially important on cars that may have had wheels changed during earlier restoration work or converted from one construction type to the other.
What does 650-16 mean on a 1950 Bentley Mark?
650-16 is a vintage numeric bias-ply tire size. The 650 refers to an approximate 6.50-inch nominal section width, and the 16 refers to the wheel diameter in inches. On a 1950 Bentley Mark, it represents the traditional bias-ply fitment path and is available in both blackwall and wide whitewall styles.
That older sizing format matters because it points to a different tire construction and appearance than a radial like 185R16. Buyers comparing the two should look beyond diameter alone and verify wheel width, intended presentation, and whether the car is being maintained as a period-style restoration or driven with a more modern touring emphasis.
Bias-Ply & Radial Options
Is 650-16 a bias-ply or radial tire for the 1950 Bentley Mark?
650-16 is a bias-ply tire size for the 1950 Bentley Mark. It uses the older numeric sizing system and is offered in classic bias-ply series with traditional blackwall and wide whitewall presentations, making it the more restoration-oriented of the two primary tire directions available for this application.
Choosing 650-16 keeps the car in a conventional bias-ply format, but that does not mean every 650-16 is the same in look or wheel requirement. Compare the sidewall treatment, tire series, and rim-width specification of the specific tire under consideration, especially if the Bentley has been updated at some point with different wheels.
Should I use bias-ply or radial tires on a 1950 Bentley Mark?
A 1950 Bentley Mark can be equipped with either 650-16 bias-ply tires or 185R16 radial tires, so the decision comes down to the car’s purpose and setup. Bias-ply construction supports a more traditional period-style presentation, while 185R16 gives the car a radial-format option that still stays within the correct 16-inch rim diameter family.
The best choice depends on whether originality of appearance, general road use, or a balance between the two matters most. Wheel width should be checked before making the change, and any shift from one construction type to the other deserves a close look at clearance, suspension condition, and the car’s overall stance.
What should I check before converting my 1950 Bentley Mark from bias-ply to radial tires?
A move from 650-16 bias-ply to 185R16 radial on a 1950 Bentley Mark starts with the wheel itself. Both sizes use a 16-inch rim, but radial products in this application carry their own rim-width requirements, so the existing wheels need to be measured rather than assumed to be suitable.
It also helps to inspect steering and body clearance, since a different construction can change how the tire sits and behaves on the car. Look over suspension wear, verify that all four wheels match, and choose the conversion only after confirming that the Bentley’s current setup supports the radial size being considered.
Choosing the Right Tire
What should I consider when choosing a 650-16 tire for a 1950 Bentley Mark?
Start with the fact that 650-16 is the bias-ply fitment path for the 1950 Bentley Mark. From there, the most important choices are sidewall appearance, tire series, brand preference, and wheel compatibility, since this size is offered in blackwall and wide whitewall versions across several classic-style product lines.
A restoration-minded car may call for one visual treatment, while a driver-focused Bentley may simply need a clean blackwall bias-ply. It also helps to compare the specific rim-width recommendation of the tire being considered, because some 650-16 products are aimed at slightly different wheel setups within the same nominal size.
What sidewall styles are available for 1950 Bentley Mark tires?
Sidewall choice depends on the size and construction you select. The 185R16 radial options are blackwall tires, while the 650-16 bias-ply range includes both blackwall and wide whitewall styles. That gives the 1950 Bentley Mark owner a meaningful appearance decision, especially on a restoration-oriented car.
A blackwall usually keeps the presentation understated and formal, while a wide whitewall brings a stronger period-style statement. Sidewall appearance should be chosen only after the correct size and construction are settled, since visual preference alone does not override wheel-width requirements or the broader question of bias-ply versus radial setup.
What brands offer tires for the 1950 Bentley Mark?
The 1950 Bentley Mark has tire options from several brands. In 185R16 radial form, choices include Michelin, Avon, and Vredestein. In 650-16 bias-ply form, options include BFGoodrich, Coker Classic, Firestone, Garfield, Excelsior, Lester, Goodyear, STA, and Tornel across a wide range of classic-style tire series.
Brand choice is only one part of the decision. It should be weighed alongside the construction type, the sidewall style you want on the car, and the wheel dimensions already on the Bentley. Comparing those factors first usually narrows the field more effectively than choosing by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1950 Bentley Mark?
For a period-style 1950 Bentley Mark, the 650-16 bias-ply size is the natural starting point because it preserves the older numeric format and traditional tire construction associated with the era. Within that size, blackwall and wide whitewall versions are both available, along with several classic bias-ply series and brand choices.
The final appearance decision depends on how the car is being restored and presented. If exact originality matters, compare the tire choice against marque references, archival photography, and restoration records for the specific car. That keeps the result historically grounded while still working within the correct primary fitment family.
How does tire construction affect the appearance of a restored 1950 Bentley Mark?
Tire construction changes the visual character of a restored 1950 Bentley Mark as much as it changes the tire category. A 650-16 bias-ply keeps the car in a traditional vintage format, while 185R16 introduces a radial profile and a more modern-looking sizing convention even though both use 16-inch wheels.
That difference matters on a car where wheel opening shape, stance, and sidewall treatment all contribute to the finished presentation. Buyers aiming for a more formal period-style look often begin with the bias-ply route, while owners prioritizing road use may accept a more modern radial appearance in exchange for that construction change.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1950 Bentley Mark?
Yes, modifications can affect tire fitment on a 1950 Bentley Mark even when the car stays with a 16-inch rim. Aftermarket wheels, changed wheel widths, suspension work, or body alterations can all influence whether a 650-16 bias-ply or 185R16 radial is the more appropriate direction for the car.
A Bentley that has been restored over several decades may not still match its earlier tire setup. Measure the wheels, check steering travel, and inspect clearance at the fenders and suspension before settling on a size. That is especially important when moving between bias-ply and radial construction or replacing older nonmatching tires.
What should I inspect before driving a 1950 Bentley Mark on new tires?
Before driving a 1950 Bentley Mark on new tires, inspect the wheels for correct diameter and width, then check that all four tires match the intended setup. It also helps to look over valve stems, wheel condition, and the general state of the suspension and steering components on a car of this age.
Once the tires are mounted, verify inflation, watch for any signs of rubbing, and recheck the car after a short initial drive. A collector car that sees infrequent use can hide problems such as aged bushings, brake drag, or uneven ride height, all of which can affect how a fresh set of tires behaves.
How should 650-16 or 185R16 tires on a collector 1950 Bentley Mark be maintained?
Collector-car tire maintenance starts with regular visual inspection, even if the 1950 Bentley Mark is driven only occasionally. Check for cracking, cuts, bulges, uneven wear, and air loss on both 650-16 bias-ply tires and 185R16 radials. Tire pressure should be monitored consistently rather than only before long trips.
Storage conditions matter as much as mileage on a low-use Bentley. Keep the car away from prolonged sun, excess heat, moisture, and ozone-producing equipment, and roll or drive it periodically so the tires are not left sitting in one position for extended periods. That habit supports both appearance and road readiness.
